Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

8-amino-5-ethyl-3-methyl-3H,4H,5H-pyrazolo[3,4-c]quinolin-4-one (CAS 1189306-45-3), molecular formula C13H14N4O and molecular weight 242.28 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 8-amino-5-ethyl-3-methyl-3H,4H,5H-pyrazolo[3,4-c]quinolin-4-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 242.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), 8-amino-5-ethyl-3-methyl-3H,4H,5H-pyrazolo[3,4-c]quinolin-4-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
